#OpenDnD monster: The Crystalbound Shark
The crystalbound shark has been bent to the will of an
artificer or other magic wielder, often an evil one, by the use
of the control crystal in its head, which also allows it to control
other sharks and fire a radiant 'laser' at enemies. They are
often found in pools hidden beneath pit traps in secret lairs in
extinct volcanos, sometimes in large numbers, almost always
with other sharks.
